Yes, and there is a connection.

In Superman 167 (February 1964), the “Metropolis Mailbag” contained this special announcement:

“Shortly after the first ‘Brainiac’ story appeared in ACTION COMICS, in 1956, we learned that a REAL ‘Brainiac’ existed…in the form of an ingenious ‘Brainiac Computer Kit’ invented in 1955 by Edmund C. Berkeley. Mr. Berkeley is a distinguished scientist and a world authority on automation, computers, and robots.

“In deference to his ‘Brainiac,’ which pre-dates ours, with this issue of SUPERMAN we are changing the characterization of our ‘Brainiac’ so that the master-villain will henceforth possess a ‘computer personality.’ We are confident that our readers will approve of this transformation; it should make ‘Brainiac’ a mightier adversary for the Man of Steel.

“Readers will be interested to learn that they can build their own ‘Brainiac’ by purchasing one of Mr. Berkeley’s computer kits and assembling the parts. Thousands of youngsters, as well as adults, have bought these kits and, by following the simple directions, have been able to construct home-made computers which can solve interesting problems of all kinds. ‘Brainiac’ kits cost less than $20.00 and make an ideal educational hobby. For more information, write for free literature to: Berkeley Enterprises, Inc., 815 Washington Street, Newtonville 60, Mass.”

So the existence of thethe Brainiac kit effected the transformation of the DC Comics Brainiac, forever changing the labyrinthine course of Superman history. To echo the Golden Age Brainiac, Ha, ha!
